BRAKE-BEAM.`

To all 'whom it may-concern:

Beit known thatfI, HENRY ZrEMss, Jr., a

citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certam new and useful .Improvements in Brake-Beams, of which the following is aspecilicat-ion.

Oneof the objects is to providean 1mprovedy connection between the brake head andthe beam.

A further object is to improvethe means for holding the brake head in adjusted anmy invention. Fig. 3 is a section vgular position upon the beam.

In the accompanying drawings, Figures 1- and. 2 are side and end views, respectively, of a brake head embodying the features of through the brake head on line 6-6 in Fig. 2. Fig. 4 is a sectional view illustrating the construction of the ends of the brake beam and theconnection between the beam and the brake head. Figs. 5 and 6 are sectional views illustrating the manner of connecting and disconnecting the brake head and the beam. Fig. 7 is a fragmental detail of an alternative construction. I

In the periphery of the sleeve 16, whlch is arranged upon the ends of the compression member 1 and tension member 2, is a v3.0

groove 20 y extending part way around the sleeve, the bottom of the groove at the ends l illustrate the invention is a casting comprisling the face 23, the hub 24 andthe side flanges 25. .Said hub is adapted to be slipped-upon the sleeve 16. Upon the inner periphery of the hub, and in this instance,

, at the vforward s'ide thereof,v is a yboss 26 adapted to lit within the groove 20'. -Upon the inner periphery of said hub 24 at the rear side thereof may be'formed a series of corrugations 27 to mesh with the corrugations 21 on the sleeve 16 and thus 'assist to hold the brake head yieldingly in place upon the 'bea't g The rake head is provided .with an eye to receivethe usual brake hanger. The eye Specification of Letters Patent.

is usually a portion of the casting extending from one flange to the other. As herein shown, however, a slot 28 is formed through the eyev adjacent each side of the ange therefore the eye may be said to consist of the openings 29 in said side flanges and the portionBO, (Figs. 2 and 3). Said portion is connected with the hub by means of the webs 31 and 32, said webs being 1formed by providing an4 opening or slot 33`extending from-the interior of the eye to the interior of the hub. It will thus be seen that the hub is split at one side, as represented in Figs. 1 and 3.

In casting'the brake head, the hub is made of such diameter that when forced upon the sleeve 16 the hub shally be somewhat expanded, the elasticity of the metal thus causing the hub to embrace the sleeve with a'` degree ofl pressure depending upon the relative proportions of the parts. The eye portion 80, because of its circular form and its connection with the hub through the WebsBl and 32, yieldingly connectsthe split sides of the hub together. p If desired, the eye portion 30 may be dispensed with'and the split sides of the ,hub resiliently connected together through the ymedium of an annular steel spring 314 (Fig.

7,).- ySaid spring, as hereinl shown, is: 1n the form of a split ring, the ends ofthe ring bearing uponl the webs 31 and "32, andthe ring being held from displacement by means of tl'le'projections 35. f *I if* If desired, niea'ns'may bel vprovided for adjusting the clamping press'ureof 'the hub 24'upon the sleeve, as, for example, a bolt 36 extending through thewebs 31 and I32. Said boltis provided witha nut37lf It will be understood that the boltand-'nutconstitute means'for increasing'the pressure of the hub to the point where'the head is immovably secured upon the sleeve, if it be desired to iiX the head in position.

When thev brake head is to be placed .upon the' beam, the brake headis placed against the outer end of thesleevewiththe boss 26 on the', lower'part of the inclined surface 22, asxshown in-Fig.` 4. Said headmay lnow be lforced in a straight line onto the sleeve, the hub expanding as the boss 26 rides up the incline 22. When said boss has passed the highest point of the incline, it drops into the groove 20. The resiliency of the met-al of the hub and the interengagement Patented Deavsgieia.

In Fi 4 a washer 13 is mounted on theend of t e tension member 2 and provided with an extension 14 forming a seat for the end ofthe compression member. A nut 15 secures the tension and compression mem,

vbers togethen'- The sleeve 16 is arran ed upon the end of the compression mem'er and is rovided with an inclined end wall 17 whic bears against the nut15. The nut 18 is screwed upon the outer end of the tensionmember to hold the `sleeve 16 in place.-

This construction just above described is not claimed in this application, but forms the subject matter of separate co-pending applications tiled Cctober '21,' 1908, .Serial No. 458,804, and a co-pending application filed February 12, 1912, Serial No.- 677 ,035.

What II claim is:

1. A brake beam comprising a member having a groove extending around a portion of its periphery, one `end of said groove merging into saidl periphery, and a brake head havinga s lit hub adapted-to itl on said member, sai hub havinga boss on its inner periphery adapted to lie in said groove on the side adjacent the yshoe supporting portionlof the head.

2. A `brake beam ,comprising a member having a groove extending around a portion of its periphery, one endof said grove merging into saidperiphery, said member having aninclined surface extending from one end thereof to said groove, and a ,brake head having'a splithub adapted to lit on said member, said hub having a boss on its inner periphery adapted toflie in said groove, said boss riding up said inclined surface when ghe brake head is being placed on said mem- '3. A brake head having a hub and la hanger-attaching eye, webs extending between said hub and said eye, said webshaving, a slot between them connecting the interiors of said hub and said eye. a

4. A brake head having a hub and a hanger-attaching eye, webs extending between said hub and said eye, said webs 4hav- 1ng a slotbetween them connecting the interiors of said hub and said eye, and-means for drawing said webs together.
